This cord on Amizon says it can do both 240 and 120. It appears to have a
short extension cord that takes the 240v 20A plug on the EVSE and converts
it to a 120v 20 amp plug. But it is impossible to see from the photo since
the view of the plug that should be the 120v 20A plug could be upside down
or right side up. And that makes all the difference in the two blades?
